This book was first published in 1997 although it has been fully revised and updated. The KC-135 is of course not just a tanker. There are many variants and all of these are covered in detail. This guy is not a jobbing aviation writer but luckily someone who is obsessed with this aircraft. There is so much detail that we could do with another book to guide you through this one. Fine there is an index and a guide to using this book. This aircraft has been around a long time and it has been put to many uses, and that being so, the author has a lot to say, covering each and every variant. The text goes into minute detail, of not only the development, but also the operational history of each variant and this is accompanied by a huge number of photographs and tables. These include Planned RC-135 Missions to and from the UK, August 1971, Mission Design Series (MDS), a list that takes up no less than fourteen pages. There is an Attrition list, another fourteen pages, and even a retirements list. Get the message? And that is just some of them. You will also find two pages of SAC tail markings and lots more.
